Variability of primary production and air-sea CO2 flux in the Southern Ocean

Description:

Biogeochemical cycling in the Southern Ocean (SO) plays a key role in the global sea-air CO2 balance and in the ocean anthropogenic carbon inventory. Some previous studies suggest a decreasing trend in the Southern Ocean carbon sink. In this study researchers investigate the interannual and decadal variations in sea-air CO2 flux and phytoplankton production in the SO with hindcast simulations by an ocean biogeochemical model.
